' BOAT-HULL.

Specification of Letters Patent.

or AnrnA, INDIANA.

- Application filed June 27, 1917, Serial No. 177,315. Renewed JulylB, 19 18. Serialjo. 245,770.

Be it known that L-WILLIAMIOLCAMP BELL, a citizen of the United States, andresident of the city-of Aetna, in the county' of Lake and State of Indiana, have invented certain new and useful Improvements in 5 Boat-Hulls, of which the following is a accompanymg drawings, forming a part- My invention relates'to improvements in I boat hulls-wherein the siding consists of i open-work metallic sheathing secured tothe framing and to which a filler or body is applied in a plastic condition and which when set is impermeable to Water. I My object is to provide a boat hull'of inexpensive and'durable construction whose which,

" tion of a boat hull embodying my'nnprove,

siding is readily obtainable and more readily and quickly applied to the frames or' skeletons of boats than the materials now employed and which siding is of relatively light weight, possessive of relatively high resistance to penetration, possessive of good resistance to the deteriorating action of the elements and which may be easily and quickly repaired.- My invention consists in the arrangement, construction and combination of elements as will be fully, clearly and concisely set forth, pointed out in my claims and illustrated in the accompanyingv drawing, in.

Figure 1 is a transverse sectional elevaments.

Fig. 2 is a fragmental elevatlon of the I hull, and

Fig. 3 isan enlarged fragmental, sectional detail View, showing one form of means for securing the metallic sheathing to the hull frame and the relation of the filler the sheathing. i Y 7 Referring to the drawings, by numerals,

5 designates the keel of the bull or VESSEL] preferably consisting of a metallic beam of T-shape, sectionally and extended as a single piece, or -rigid1y connected sections throughout the length of the hull, or fromstem to stern and to which the lower ends extend in opposite directions transversely" of the hull and from the keel, as single pieces, or rigidly connected sections of angle irons to the rails 7 of the hull, and which tinuous from railto rail ofthe' hull, which Patented Febi25, 191s.

connected held relatively isv my preferred construction and while I preferably continuous from stem 'to-stern. 1 r

Obviously, in relatively large hulls, it would be diflicultto make one section or plece of sheathing cover the entire hull, in

have not illustrated the same I prefer that such plies are also" which case I- connectsections of sheathing in a manner tov produce'the effect of a con-.{f

tinuous, onepie'ce. sheathing, by whichex1 pedientl may in .some cases,'*dispense en 1- tirely with stringers between r bs, as is ccmmon.

To this sheathing I apply a vfiller or body 12, comprising pulp or fiber and a binder which formsa'j plastic masswhich maybe readily forced through the interstices .of'the sheathing and a here thereto to form therewith a reinforced body, and in a manner to completely embed both the sheathing and its means of attachment or securement to the hull frame.

Inorder to render the mass compact and intimately contact with the sheathing, the filler may be tamped during its application.

The filler or body 12 may consist of easily obtainable and inexpensive material, such as sawdust, wood-pulp, wood-fiber, vegetablefibers of varlous varieties, as well as various mineral and animal fi'bers, and. the binder may be any waterprooftenacious substance, such as white lead orlitharge oil, or waterproof glue.

Having thus describedmy invention what I claim as new therein and desire to secure by Letters Patent, is-

sheathing secured to the ribs, the said sheath- 'mixed; with 1. A boat hull comprising side ails,- stanchions secured to said side rails, a keel ing being" spaced apart,'and a body of fibrous material and] tenacious water-proof material pressed between the metallic sheathing and entirely covering same.

2. A boat hull comprising a metallic keel,

side rails and stanchions connecting the side rails, ribs secured to the side rails and keel,

a plurality of open mesh, layers of metallic sheathing spaced apart secured to said ribs, and a plastic wood fiber pulp mixed with a water-proof material pressed between the layers of metallic sheathing.

3. A boat hull comprising a metallic'keel; side rails and stanchions, ribs connected to. the side rails and keel, a series of layers of openmetallic sheathing spaced apart secured to the ribs, and a plastic body consisting of wood pulp and white lead pressed between the sheathing and covering the outside sheathing.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing Witnesses.
